Magnitude: Brightness (lower = brighter). Venus can reach −4.6; naked eye limit is ~6.
Altitude: Height above horizon in degrees. 0° = horizon, 90° = directly overhead.
Observing conditions: Opportunities require the planet above 5° and Sun below −6°, sampled every 15 minutes over the next 24 hours. Clouds, light pollution and glare may prevent visibility. Positions are geometric, without atmospheric refraction. Elongation: Angular distance from the Sun. Larger values mean better visibility at night.
Constellation: Approximate zodiacal constellation the planet is currently in.
